Timing and Adjustment mechanical watch movement - Running fast or slow

[Music] [Applause] [Music] [Music] hi there everybody and a special welcome to all the new subscribers thank you so much for your support and i really do hope uh you like the content on our youtube channel chronoglide um this time timing uh timing a watch i'd like to show you how to do that and a bit more theory but i know it's going to be worth it so bear with me we're going to have fun here you can see the balance wheel the balance spring and the escapement here the pellet fork and the escape wheel there are only two ways to time your movement and that is by adjusting the length of your balance spring and adjusting the weight of your balance ring and that's here but as you can see this balance ring hasn't got any screws or weights so with this particular movement you can only adjust the length the working length of your balance spring i know the terms balance spring and hair string are commonly used but there's a beautiful definition plaque in the science museum in london whenever you got a chance please visit the science museum in london it's beautiful london england um the definition is very clear this balanced spring is a hairspring well that sounds silly but [Music] maybe the easiest every poodle is a dog but not every dog is a poodle this battle spring is a hair spring but not every hair string is a balance spring a hairspring only says it's a very small tiny spring with a particular function and this hairspring happens to be a bevel spring i do hope that makes sense so but uh i often make a mistake as well we've been calling it a hair spring for a very long time but it is true i think the official name will be balanced spring that happens to be a hairspring um for the timing i would like to take take one step back and show you a tiny bit of theory dutch theory and then it's so much easier to see what we're doing in the timing so a bit of theory well what we got here is a very happy apple charger isaac newton using apple why don't we use an apple charger well i was calling it dutch theory because this man the man and his wig is christian haugens and he came up with a brilliant concept he made the first physics law and that is the pendulum law of hypens and it sounds kind of hard to follow it is that simple once you've seen it the first physics law made by hyphens is that the amplitude of the pendulum doesn't affect the the time it takes to go back and forth it's a bit simple but i hope that makes sense simplified but i hope it makes sense and that is once you've seen it it's that simple amplitude is this in degrees and his physics law was tick tock tick tock low amputee amplitude is exactly the same as tick tock tick duck makes sense small amplitude tick tock tick tock it's the same as tick tock tick tock so the amplitude won't affect the time it takes to go back and forth the only way you can change the rate is by making it smaller go fast or making it longer pendulum slow so if you've got a pendulum like this the only way to affect the rate going fast or slow is by changing the length of the pendulum fast slow and a pendulum is exactly the same as a balanced spring in a watch movement so if we make the balance spring shorter it will go fast if we make it longer it will go slow one thing is a term you have to remember is that the end bit i'm holding here is called the stud in dutch the piton and that is the end bit of the pendulum and once you see that it will make sense well do you see here the stud the piton and that is the end bit of the pendulum the end and here it goes inwards inwards inwards and here are the timing pins in touch compos and that is simply the sliding bit to make the pendulum or balance spring longer or shorter there are only two ways to affect the rate of a watch movement because the rest are gear ratios and you cannot make some gears or teeth go away so you cannot change the gear you can but for the timing you will not change the gear ratio so all the timing is done in the length the effective length of your balance spring and again i will show you later on there's a second way of timing a watch and that is by this the weights in the balance ring but here it's just the timing pins of the balance spring i do hope that makes sense and once you have got a visual of the apple charger with the timing pins making it shorter and longer same here we have timing pins please use a soft material like plastic or wood so you don't make any scratches here you can see now i'm making the pendulum longer i'm going two words towards the stud the end bit and now get rid of the fiber and now we make the pendulum shorter because we go away from the studs the end beads see that so now we make the pendulum shorter and it will go fast shorter fast longer slow and if you visualize the pendulum i think that will make sense underneath here the timing pins are two actual pins sliding side by side of the balance spring and here you see usually or the f from fast usually you see them there that's simply the meaning of those letters so that's how you time your movement by simply sliding the timing pins next to the balance spring what happens to be a hair spring the second way of changing the timing of a movement you can see here you see here in a rolex you can see here the weights in the balance rim and here you can see only the stud the end of the pendulum the end bit here so no timing pins same compos so by changing these weights in and out you can change the timing and most of my students already see me do this once you see it it is that simple bear with me fast slow fast slow fast i hope did that make sense in order to make the weights go outwards or inwards rolex has made a small tool well this is the rolex tool and here you can change the position of the weights it's crucial that the position of the weights on both sides stays the same otherwise you create an imbalance absolutely crucial well here you can see there the shape of the small screw and here you can see the actual degrees you're removing it with the weight so you know exactly on both sides the same amount of angle in degrees you give it well this tool well well this tool is patented by rolex so no one can use this particular tool so omega has made a completely different tool for their coaxial and it is different because there is a square for the for the weights but otherwise you see a completely different tool one last well warning when you time your mechanical watch movement you can push here with a soft material like some peg wood or here's some plastic so you don't make any scratches but sometimes you have to push here be very very very careful because if you damage the hair stream well you don't have to time it again [Music] but it is very fragile so be very careful when adjust your timing pins over here it's more safe to do it over here but sometimes it is a a bit more difficult well i do hope that makes sense the length of the pendulum makes it go fast or slow when you go close to the stud and go fast because the effective length is longer and if you go the other way it will run fast and i hope you remember if the weights go in you go fast and if the weights go out you go slow i do hope that makes sense um and please be very careful with the hairspring which is a balanced spring [Laughter] because it is very fragile please try this at home if there are any questions please leave them in the comments or suggestions for future topics or things you've seen and not quite clear please let me know thank you for attention and thank you for your support i really enjoy reading the comments and hope to see you soon see ya bye [Music] you
